<p> The purpose of this study was to determine if a single inertial measurement unit (IMU) could be used to estimate the vertical ground reaction force (vGRF) of a vertical jump. To do this 16 college-age participants (8 female, 8 male) preformed three counter movement jumps, three drop jumps, and three squat jumps. All jumps were simultaneously recorded with a force plate (1250 Hz) and an IMU (128 Hz) placed on the sacral-L5 junction. The peak rate of force development, reactive strength index, jump impulse, jump height determined from impulse (h<sub>imp</sub>), jump height determined from flight time, and peak force were measured using both the force plate and IMU. There was a significant difference between measuring devices for all dependent variables (p < 0.05) except the h<sub>imp</sub> (p = 0.341). In conclusion, this study does not provide a means of accurately estimating vGRF using an IMU.</p>
